A horizontal force pulls a box along a horizontal surface. The box gains 30J of kinetic energy and 10J of thermal energy is produced by the friction between the box and the surface. How much work work is done by the force?​

Answer:

Work = Change in Kinetic Energy + Thermal Energy

Work = 30 J + 10 J

Work = 40 J

Therefore, the work done by the force is 40 J.
